<p>My theory by A. Elk.  Brackets Miss, brackets.  This theory goes
as follows and begins now.  All brontosauruses are thin at one
end, much much thicker in the middle and then thin again at the
far end.  That is my theory, it is mine, and belongs to me and I
own it, and what it is too.</p>

<pre class="code python literal-block"><code>print 'This is Python code.'</code></pre>
<p>The <span class="docutils literal"><span class="pre">:number-lines:</span></span> option (with optional start value) generates line

<p>For inline code snippets, there is the <cite>code</cite> role, which can be used
directly (the code will not be parsed/tagged, as the language is not known)
or as base for special code roles, e.g. the LaTeX code in the next

<h2><a class="toc-backref" href="#id78"><span class="sectnum">2.24</span> SVG Images</a></h2>
<img alt="../../../docs/user/rst/images/biohazard.svg" class="align-left" src="../../../docs/user/rst/images/biohazard.svg" style="width: 48px; height: 48px;" />
<p>Scalable vector graphics (SVG) images are the only standards-compliable way
to include vector graphics in HTML documents. However, they are not
supported by all backends/output formats. (E.g., LaTeX supports the
PDF or Postscript formats for vector graphics instead.)</p>
<p>Rendering behaviour varies, depending on</p>
<ol class="loweralpha">
<li><p>The SVG image itself, e.g. fixed-size vs. scaling:</p>
<pre class="literal-block">width=&quot;280&quot;              viewBox=&quot;0 0 280 27&quot;
height=&quot;27&quot;              width=&quot;100%&quot;
                         height=&quot;100%&quot;</pre>
</li>
<li><p>The method used to put the image in the document.</p>
<p>For HTML, there are several alternatives including:</p>
<ul class="simple">
<li><p>using the HTML <span class="docutils literal">&lt;img&gt;</span> tag (not for interactive/animated SVG),</p></li>
<li><p>using the HTML <span class="docutils literal">&lt;object&gt;</span> tag,</p></li>
<li><p>including within SVG using the SVG <span class="docutils literal">&lt;image&gt;</span> tag,</p></li>
<li><p>embedd the SVG code within HTML (inlining).</p></li>
</ul>
<p>The <cite>html4css1</cite> writer uses <span class="docutils literal">&lt;object&gt;</span> tags, the <cite>html-base</cite> and <cite>xhtml11</cite>
writers use <span class="docutils literal">&lt;img&gt;</span> tags.</p>
<!-- cf. http://edutechwiki.unige.ch/en/Using_SVG_with_HTML5_tutorial -->
</li>
<li><p>The viewing agent.</p>
<p>All up-to-date HTML browsers support SVG, however not all do this fully
and in the same manner. Many older versions, especially IE &lt; 9, have
deficiencies or require plug-ins (i.e. don't support the <span class="docutils literal">&lt;img&gt;</span> tag).</p>
</li>
</ol>
<p>If the image is wrapped in <span class="docutils literal">&lt;object&gt;</span> or <span class="docutils literal">&lt;svg&gt;</span> tags, it depends on the
<span class="docutils literal">viewBox</span> declaration inside the images root <span class="docutils literal">&lt;svg&gt;</span> element whether an
SVG image is scaled or clipped/padded. Images wrapped in <span class="docutils literal">&lt;img&gt;</span> are
always scaled.</p>
<ul>
<li><img alt="../../../docs/user/rst/images/title-scaling.svg" class="align-right" src="../../../docs/user/rst/images/title-scaling.svg" style="width: 50%;" />
<p>A scaling image (scales with the browser window), occupying 50% of the line
width. The <span class="docutils literal">viewBox</span> setting in the image file enables auto-scaling also in
<span class="docutils literal">&lt;object&gt;</span> tags and embedded SVG (if width and hight are set to 100% in the
SVG &lt;image&gt; tag).</p>
</li>
<li><img alt="../../../docs/user/rst/images/title.svg" class="align-right" src="../../../docs/user/rst/images/title.svg" style="width: 50%; height: 15px;" />
<p>A fixed-size image in a box 50% wide and 15 pixles high. This image is
scaled, if wrapped in an <span class="docutils literal">&lt;img&gt;</span> tag but clipped in an <span class="docutils literal">&lt;object&gt;</span> tag
or within SVG.</p>
</li>
<li><img alt="../../../docs/user/rst/images/title-scaling.svg" class="align-right" src="../../../docs/user/rst/images/title-scaling.svg" style="width: 50%; height: 1.5em;" />
<p>A right aligned, scaling image 50% wide and 1.5 em high. (This SVG image
keeps the aspect ratio.)</p>
</li>
<li><p>An inline image <img alt="inline-svg" src="../../../docs/user/rst/images/biohazard-scaling.svg" style="height: 0.8em;" /> scaled to a height of 0.8 em.</p>
</li>
<li><img alt="../../../docs/user/rst/images/biohazard-scaling.svg" class="align-right" src="../../../docs/user/rst/images/biohazard-scaling.svg" style="height: 1em;" />
<p>A scaling image 1 em high, right aligned:</p>
</li>
<li><p>A scaling image 5 mm x 5 mm, centered, with hyperlink reference:</p>
<a class="reference external image-reference" href="SVGImages_"><img alt="../../../docs/user/rst/images/biohazard-scaling.svg" class="align-center" src="../../../docs/user/rst/images/biohazard-scaling.svg" style="width: 5mm; height: 5mm;" /></a>
</li>
<li><img alt="../../../docs/user/rst/images/biohazard.svg" class="align-right" src="../../../docs/user/rst/images/biohazard.svg" style="width: 4cm; height: 2em;" />
<p>A fixed-size image in a  4 cm x 2 em box.</p>
</li>
</ul>
<p>Older versions of <cite>webkit</cite> based browsers (chromium, safari, midori,
konqueror) support the <span class="docutils literal">&lt;img&gt;</span> tag but don't display contained bitmap
images in this case.</p>
<ul>
<li><img alt="../../../docs/user/rst/images/biohazard-bitmap.svg" class="align-right" src="../../../docs/user/rst/images/biohazard-bitmap.svg" style="width: 3em;" />
<p>A small, fixed-size SVG image with embedded bitmap, The <span class="docutils literal">:width:</span> is
set to 3 em in the rST source. Does not scale if wrapped in <span class="docutils literal">&lt;object&gt;</span>
tags.</p>
</li>
<li><img alt="../../../docs/user/rst/images/biohazard-bitmap-scaling.svg" class="align-right" src="../../../docs/user/rst/images/biohazard-bitmap-scaling.svg" style="width: 3em;" />
<p>A scaling SVG image with embedded bitmap, 3 em wide.</p>
</li>
</ul>
<p>SVG images can also be put in figures:</p>
<blockquote>
<div class="figure align-center">
<img alt="reStructuredText, the markup syntax" src="../../../docs/user/rst/images/title.svg" style="width: 290px; height: 28px;" />

<p>The following list demonstrates the problems with the html4css1

characters&quot; but the field name uses a proportional font.</p>
<dl class="field-list simple">
<dt>The field name</dt>
